GMG Roof Experts, the leading roofing company in London, offers top-tier roofing solutions tailored to your specific needs.
GMG Roof Experts carry out roof repair and installation across the whole London Borough of Hillingdon. We fix slipped and broken tiles, failed flat roofs, leaking valleys and worn flashing, and where a roof is past repair we strip it and install a new one on fresh underlay and battens. Pitched or flat, tile, slate, felt or lead, from a single-tile fix to a full re-roof on a Victorian terrace or a new roof on an extension, we work from our Hayes UB3 base across Uxbridge, Hayes, Ruislip, Ickenham, Northwood and every postcode in between.
The background
Hillingdon's housing stock is a mix of Victorian and Edwardian terraces around Uxbridge and Yiewsley, 1930s Metroland semis across Ruislip, Eastcote and Northwood, inter-war and post-war terraces through Hayes and Yeading, and later infill and extensions everywhere. The roofs on all of them are now decades into their service life, and most repairs we are called to come down to the same handful of causes: a covering that has simply worn out, a detail that was never right, or weather that has found the weakest point.
A pitched tile or slate roof fails tile by tile. Nibs and nails corrode, tiles slip, the mortar bedding on the ridge and hips cracks and lets tiles rock loose, and the felt underneath tears so that wind-driven rain gets past the covering. A flat roof fails differently, with ponding water, splits and blisters in the old felt, and lifted upstands where it meets a wall. Lead valleys, soakers and flashings crack along the fold lines and pull away from the brickwork.
The judgement on any given roof is whether targeted repairs will give it years more life or whether it has reached the point where a full strip and re-roof is the better value. We give you that assessment straight, with a written quote either way, and we never sell a re-roof where a repair would have done.
We are based in Hayes, we carry out roof repairs and installations across Hillingdon every week, and we have handled everything from a single slipped tile to a complete re-roof and a new roof structure on an extension.
What we do
From a single slipped tile to a full re-roof and new roof structures on extensions, every job below is carried out by our own team, not subcontracted out, and every one starts with a close-up inspection and a written quote on request.
Slipped, cracked and missing tiles or slates, corroded fixings, torn underlay and rocking ridge tiles. We trace the leak, not just the stain, and repair with matched materials.
Ponding, splits, blisters and lifted upstands on old felt roofs over extensions, garages, dormers and bays. We patch where it makes sense and recover where it does not.
Where a covering is worn out, we strip the roof, renew the underlay and battens, and re-lay in matched or upgraded tiles or slates, with new ridge, hip and verge systems.
Matching individual tiles and slates to age, colour and profile, or re-covering a whole slope where too many have failed to make piecemeal repair worthwhile.
Cracked lead valleys, failed abutment and chimney flashing, worn soakers and box gutters. We strip the old lead and re-dress new lead to code into raked joints.
Re-bedding or converting loose mortar ridges and verges to a dry fixed system, and renewing the weathering where the roof meets a chimney or a parapet.
A roof repair starts with getting up onto the roof and into the loft and finding where the water is actually getting in, not guessing from the damp patch on the ceiling. Water can track a long way between the entry point and the stain, so we check the covering, the underlay, the valleys, the flashings and the ridge before agreeing a scope of work.
Once we can see the cause, we repair with materials that suit the roof. That means a matched natural slate and copper nails on a Victorian terrace near Uxbridge High Street, matched concrete tiles on a 1930s Ruislip semi, and lead dressed to the correct code where the roof meets a wall or chimney. We do not smear mastic over a symptom and leave the roof taking water.
How it works
The process is the same whether it is a single-tile repair or a full re-roof, and it starts with a conversation, not a sales pitch.
Call 07949 999411 or use the contact form. Tell us what you are seeing inside and out and roughly where the property is in Hillingdon.
We get onto the roof and into the loft, find the cause, and send a written quote covering materials, access, labour and timescale, with repair and re-roof options where both are realistic.
Most roof work needs scaffold or a tower rather than a ladder. We arrange the right access so the repair or installation is done safely and lasts.
We complete the agreed scope, clear up and take the waste away, and give you a written summary with photographs of the finished roof.
Repair or replace
Not every worn roof needs replacing, and not every leak can be chased forever with repairs. The call depends on how much of the covering is still sound, the state of the underlay and battens, how many previous patch repairs there have been, and whether the access is already up for other work. On a roof with a handful of slipped tiles and sound felt, a repair is clearly right. On a roof where the slate is delaminating across every slope and the nails have gone, a re-roof is the honest answer and usually the better value.
We set out both options in writing where they are both realistic, so the decision is yours and it is an informed one. We record the roof before we start and re-lay to the same lines, courses and detail unless you have asked us to upgrade something.
Replacing slipped or broken tiles and slates and patching the underlay at the leak, where the rest of the covering has life left.
Stripping and re-laying one elevation where too many tiles on that slope have failed for piecemeal repair to make sense.
Complete removal of the old covering, new breathable underlay and battens, and a full re-lay in matched or upgraded tiles or slates.
Setting out and building a new roof structure and covering from scratch on an extension, garage conversion or new build.
Flat roofs over extensions, garages, dormers and bay windows have a shorter life than the main pitched roof, and they usually fail first. Old three-layer felt ponds, cracks along the seams and blisters where trapped moisture expands, and the upstand where the flat roof meets a wall lifts and lets water track behind it.
We assess whether a localised patch will hold or whether the roof needs a full recover, and we lay the replacement in the covering that suits the deck and the budget, torch-on felt, EPDM rubber or GRP fibreglass, with new upstands, drip trims and outlets so the water leaves the roof where it should.
When a roof has reached the end of its covering life, repairs stop being worthwhile. A slate roof where the nails have corroded through, a concrete tile roof that has lost its surface and gone porous, or a roof that has been patched so many times there is more repair than original, all point to a full re-roof.
We scaffold the property, strip the old covering and take it away, inspect and repair the timbers, and re-lay on new breathable underlay and treated battens. The covering goes back in matched tiles or slates, or an upgrade if you want one, with dry ridge, hip and verge systems that do not rely on mortar staying sound.
Completed work

Roof repair and installation is the core of what we do from our Hayes base, inside the borough, from a single slipped tile to a full re-roof. That means we turn up with the right access, matched tiles and slates, and lead to the correct code, and we do the diagnosis in the loft and on the roof before quoting.
Our work runs from targeted repairs on a semi to full re-roofs and new roof structures on extensions and new builds. We are CITB certified, fully insured, and work from scaffold or tower access as the job needs, we take all the waste away, and every job ends with a written summary and photographs.

Questions
The questions below come up most often from Hillingdon homeowners, landlords and businesses.
Yes. Roof repair and installation is the core of what GMG Roof Experts does. That runs from replacing a single slipped tile or slate, through valley and leadwork, ridge and verge re-bedding and flat roof repairs, up to a full strip and re-roof and building a new roof structure on an extension or new build.
It comes down to how much of the covering and the underlay is still sound. A roof with a handful of slipped tiles and intact felt is a repair. A roof where the slate is delaminating across every slope, the nails have corroded, or it has been patched repeatedly, is usually better re-roofed. We give you that assessment after inspecting the roof and the loft, with a written quote for each realistic option.
Damp patches or staining on upstairs ceilings, daylight or drips visible in the loft, slipped or missing tiles seen from the ground, granules from the tiles collecting in the gutters, and ridge tiles that look loose or have gaps in the mortar. On flat roofs, look for pooling water that does not drain, splits, blisters and lifted edges.
Yes. We repair and replace flat roofs over extensions, garages, dormers and bay windows, in torch-on felt, EPDM rubber or GRP fibreglass, including new upstands, trims and outlets and the junction where a flat roof meets a pitched roof or a wall.
Yes. We work on clay and concrete tiles, natural and fibre-cement slate, felt and single-ply flat roofs, and lead and metal detailing. We match repairs to the existing material by age, colour and profile, and we will tell you where an exact match is no longer available.
A full re-roof needs a scaffold around the property for safe access and to load out materials. A typical semi-detached re-roof is a matter of days once the scaffold is up, longer for a larger or more complex roof or if timber repairs are found during the strip. The timescale is set out in your written quote.
Yes, 24 hours a day. Storm-lifted tiles, dislodged ridge tiles, torn flat roofs and water coming into the property are the most common call-outs. The first visit makes the roof safe and weathertight, with the permanent repair or re-roof scheduled once it is secure.
Yes. A full re-roof includes stripping the old covering and underlay, inspecting and repairing the timbers, and re-laying on new breathable underlay and treated battens. Where you are upgrading loft insulation or ventilation at the same time, we will factor that into the scope and quote.
We inspect the roof and the loft in person, then send a written quote covering materials, access, labour and timescale. Where both a repair and a re-roof are realistic, we quote both so the choice is yours. All pricing is on request after that visit, because access and scope are the biggest variables. We do not give figures without seeing the job.
